Elden [556K]

Answer:

germicide removal of microbes from a limited area

Explanation:

Antisepsis refers to the practice of using an antiseptic substance to remove or destroy disease-causing pathogens.

Virucides are chemical agents that aid in the deactivation or destruction of viruses.

Germicides are chemical agents that are capable of destroying germs with germs being harmful microscopic organisms.

Disinfection refers to the action of using chemicals to clean off or destroy bacteria from an area.

Considering the definition of each term above, the mismatched pair of all the terms is germicide - germicide removal of microbes from a limited area.

Germicide is a substance and not an action.

Covalent bonds have a higher melting points than ionic bonds. True False

melomori [17]

Answer:

This statement is false.

Explanation:

Ionic bonds have relatively high melting and boiling points, compared to that of covalent bonds.

Ionic compounds have strong electrostatic bonds between oppositely charged ions. Covalent bonds, on the other hand, have weaker attractions between molecules.

Remember, the melting point, is simply the amount of heat (energy) it takes to break apart the molecular bonds. The stronger the bonds, the harder it will be to separate them!

Hope this helps! :)

Wittaler [7]

Question is incomplete, the complete question is as follows :

Clotting begins when a _________ occurs in a blood vessel wall. Almost immediately, _______ cling to the blood vessel wall and release _____________ which helps to decrease blood loss by constricting the vessel. __________ is also released by damaged cells in the area. This chemical substance causes ________to be converted to ____________. Once present, thrombin acts as an enzyme to atatch ___________molecules together to form long, threadlike strands of _________, which then traps ____________ flowing by in the blood.

Answer:

Clotting begins when a BREAK occurs in a blood vessel wall. Almost immediately, PLATELETS cling to the blood vessel wall and release SEROTONIN, which helps to decrease blood loss by constricting the vessel. THROMBOPLASTIN is also released by damaged cells in the area. This chemical substance causes PROTHROMBIN to be converted to THROMBIN. Once present, thrombin acts as an enzyme to attach FIBRINOGEN molecules together to form long, threadlike strands of FIBRIN, which then traps ERYTHROCYTES flowing by in the blood.
